Good and cheap.
Reflashed to Zigbee. Works fine in the loft so it cooks in the summer and gets very cold in the winter. Battery life is about a year.

Works nicely with Home Assistant!
Works nicely with Home Assistant via (Low Energy) Bluetooth. Has been running for a few months now with no discernible battery drain.Display on actual device is small, but readable with good light.

It’s tiny
This little thing is tiny. I’m not sure how accurate it is, but it’s cute. I would buy another one when it’s on sale, not really worth the full price.

Works with Home Assistant over Zigbee
Flashed custom Zigbee firmware on this and had it working perfectly with Home Assistant in no time. Recommended for anyone with HA.

Accurate but tiny
It seems accurate but it's worth noting just how small it is. Fine if you're connecting via Bluetooth to see readings on your phone or whatever, but not great if you want to be able to walk into a room and glance at it. I've taken a picture of it with a 50 pence piece on top for scale.Also worth noting that as others have said, it does not come with a battery.
